The Uses of 3,5-Dinitrosalicylic acid
3,5-Dinitrosalicylic acid is a salicylic acid derivative used in colorimeteric determination of reducing sugars.
The Uses of 3,5-Dinitrosalicylic acid
3,5-Dinitrosalicylic acid is used in the quantification of reducing sugars by colorimetry. It is utilized for the analysis of glycosidase (glycoside hydrolase) activity by quantitation of enzymatically released reducing sugar. It is also used to detect reducing substances in urine and for quantifying carbohydrate level in blood. It acts as an important raw material and an intermediate in the production of organic chemicals such as agrochemicals, organic synthesis, pharmaceuticals and dyes.
The Uses of 3,5-Dinitrosalicylic acid
3,5-Dinitrosalicylic acid was used as a reagent for the preparation of oxazolines from amino alcohols and for the spectrophotometric determination of ampicillin. It was also used to measure the effects of silver nanoparticles on the membrane leakage of the reducing sugars.
What are the applications of Application
3,5-Dinitrosalicylic acid is a salicylic acid derivative used in colorimeteric determination of reducing sugars
Definition
ChEBI: A monohydroxybenzoic acid consisting of 2-hydroxybenzoic acid having nitro substituents at the 3- and 5-positions. It is used in colorimetric testing for the presence of free carbonyl groups (C2O) in reducing sugars.
Biochem/physiol Actions
3,5-Dinitrosalicylic acid (DNS) is used in colorimetric determination of reducing sugars and to analyze glycosidase (glycoside hydrolase) activity by quantitation of enzymatically released reducing sugar. The dinitrosalicylic acid method has been compared to the Nelson-Somogi colorimetric method.
Purification Methods
Crystallise the acid from H2O. [Beilstein 10 IV 270.]
